In a letter to judges, Baroness Carr said she was “increasingly concerned” about threats and abuse targeting the judiciary.

“As many of you will be aware, incidents threatening or compromising judicial safety are becoming all too common, both inside and outside of the courtroom and online as well as physical. Any incident where your security is compromised is taken with the utmost seriousness,” she said.

A new “operational security” taskforce will assess both physical security measures in courts and the risks posed by online threats and abuse.

The guidance issued to judges advises: “Do not refer, or even allude, to being a judge in your social media profile or anything you post on social media.” Judges are also warned against sharing personal details, posting identifiable photos, and assuming social media interactions are private.

Judicial security protocols are being updated following a series of incidents, including an attack on senior family court judge Patrick Perusko, who was assaulted with a radiator during a hearing in Milton Keynes.

In response to growing security concerns, judges have been advised they can issue judicial orders requiring high-risk individuals to attend court remotely via video. Where courts have cells and a sufficient number of security staff, they have been reminded that contempt of court is a “valuable judicial tool” for managing disruptive behaviour.

A pilot scheme at London’s main family court which saw judges eschew formal robes to make the experience less intimidating has abandoned the change after reports of “increasingly common” violent incidents causing apprehension among the judiciary.

Sir Andrew McFarlane, the most senior family law judge, said there had been a “relatively high” number of incidents, including knives being confiscated at the court’s entrance.

Baroness Carr’s letter states: “Security training for civil, family, tribunal judges and members and coroners is due to be launched in the spring and will bring together all available guidance.

“The training will contain scenario-based examples, a video from HM courts and tribunal service security explaining their roles, as well as information from the police on identifying verbal and non-verbal cues.”
